With Progress Comes Challenge

I bet you've never thought about this: Firefighters are changing tactics and trying to come up with better ways to fight house fires now that furniture burns faster than it used to. That's because of the move from cotton and other natural substances to synthetics and plastic over the years. The burning plastic also sucks up oxygen, making the overall fires even more dangerous, because it creates a situation where the fires look like they're going out but are just waiting for a door to be opened or window to be broken before they flash up again. It's more dangerous than you thought. (New York Times)
